The first settings screen deals with monitor settings
As expected, the game has options to choose the screen resolution
You can also toggle between fullscreen and windowed—a borderless option is not available
V-sync can be turned off, but the game still has a maximum FPS limit of 120 frames per second (which can be lowered but not increased on the second settings screen)
Luminance is active when you have an HDR monitor
"FPS" lets you enable the FPS/memory/disk stats you see in the top left of all our screenshots—an extremely useful feature!
What I'm missing here is an option to adjust field of view. In third-person mode, the FOV is acceptable, but it would still be nice to dial it up a few more degrees. A first-person mode is also available in game, but its field of view is too narrow, which is no big deal since first-person mode won't be used much anyway due to the way the combat system works.
The second settings screen lets you adjust graphics details and effects
Framerate can be set to 30 FPS, 60 FPS, or 120 FPS. In the GraphicsConfig.ini file (located under My Documents\Final Fantasy XV), you can set any value, which is what we used to ensure we're not getting frame capped during performance testing.
The "Resolution" option lets you adjust the rendering resolution, so you can run at your monitor's native resolution (crisp texts and HUD), while reducing the graphics hardware requirements. Options available here are 50%, 75%, 125%, 150%, 175%, and 200%. The values above 100% can help reduce aliasing, but with a large performance hit.
"Preset" lets you choose from predefined performance presets: Low, Average, High, Highest, and Custom
See the grayed out "Assets" option? It will get enabled once you download the 4K texture pack available as a free DLC for Final Fantasy XV.
The anti-aliasing options are None, FXAA, and TAA
Most people hate motion blur, but you can easily turn it off on this page
Near the end of the page, you'll find some additional NVIDIA effect technologies that do improve image quality slightly, but the changes are not that significant.
